Ejido Tecomate Wastewater Treatment Plant, San José de Palos Blancos, Sinaloa

Ejido Tecomate is a wastewater treatment plant located in the community of San José de Palos Blancos (Palos Blancos), within the municipality of Guasave, Sinaloa, Mexico. The plant serves a small population of 548 residents, providing secondary treatment to municipal wastewater. It is situated inland, away from coastal areas, and its operations are part of the local sanitation infrastructure. The plant has a designed capacity of 51.84 cubic meters per day, with a corresponding discharge volume matching this capacity. As a secondary treatment facility, it employs biological processes to reduce organic matter and suspended solids. In Mexico, wastewater treatment plants are regulated under the National Water Law (Ley de Aguas Nacionales) and the Federal Law for the Prevention and Control of Environmental Pollution, with oversight from CONAGUA (National Water Commission). For small communities like this, secondary treatment is typical to meet basic effluent standards. The treated effluent from Ejido Tecomate is discharged into local water bodies that eventually drain into the Pacific Ocean via the Sinaloa river system. The region's watershed supports agricultural activities and diverse aquatic life. Proper treatment helps protect downstream water quality and reduces the risk of eutrophication in coastal lagoons and estuaries.

The plant discharges into local waterways that are part of the Sinaloa basin, which flows into the Pacific Ocean. The region's watershed supports agricultural irrigation and provides habitat for fish and migratory birds. Effective secondary treatment is essential to prevent nutrient loading and maintain the ecological health of downstream coastal ecosystems.
